5w... Bleeding, cramping, small clots

I'm 5w today. Yesterday I was bleeding and cramping a little lighter than a normal period for me from about noon-9p. Then it stopped. Last night and this morning, no cramping and  just lightly spotting. I pretty much prepared myself for the worst. 😩💔 
Anyone else experience this? Should I have any hope? At 5w should I still go to the doctor? I thought it was too early to detect anything via ultrasound.
